Objective To explore the effects of short-term application of rosuvastatin on LDL-C concentration and the incidence of cardiovascular events after percutaneous coronary intervention (PCI) in patients with diabetes mellitus associated with mild-moderate renal insufficiency (MMRI). Methods From Dec. 2008 to Oct. 2011, 2998 patients were enrolled from 53 centers in China for a TRACK-D project. Of them, 1590 patients to receive PCI were selected for this trial and assigned to rosuvastatin group (n=808) and control group (n=782). Patients in rosuvastatin group were treated with 10mg rosuvastatin every evening for 2 days before and 3 days after intervention. Control patients did not receive statin treatment in the 2 days before and 3 days after the procedure. The levels of LDL-C in the serum were measured before and after 72 hours of interventional treatment. The cardiovascular event rate was recorded during hospitalization and follow-up of 30 days. Results The baseline data were not significantly different (2.56±0.81mmol/L vs 2.52±0.81mmol/L, P>0.05) between the two groups. At 72 hours after PCI, the LDL-C concentration was lower in rosuvastatin group than in control group (2.12±0.67mmol/L vs 2.61±0.67mmol/L, P<0.01). The difference in LDL-C between post- and pre-operation were -0.42±0.59mmol/L vs 0.09±0.54mmol/L in rosuvastatin group and control group respectively and statistically significant (P<0.01). During the hospitalization and follow-up period of 30 days, the incidence of cardiovascular events was lower in rosuvastatin group than in control group (3.3% vs 4.9%, P=0.127), without significant difference. Conclusion The short-term application of rosuvastatin during the perioperative period in the patients with diabetes mellitus associated with MMRI (stages 2-3) can reduce LDL-C concentration and the incidence of cardiovascular events.

OBJECTIVETo determine the dynamic expression of survivin gene in hepatocarcinogenesis of rats induced by aflatoxin B1 (AFB1).

METHODS78 Sprague-Dawley rats were used in this study. Hepatocellular carcinoma was induced in the rats by aflatoxin B1. Liver and HCC tissues were examined by immunohistochemistry and reverse transcriptase-polymerase chain reaction (RT-PCR).

RESULTSThe earliest hepatocellular carcinoma occurred at 46th week after AFB1 treatment. The HCC incidence was 54.9% (28/51) at 46th week and 64.9% (24/37) at 58th week. The positive rates of survivin protein expression in 24 HCC, para-cancerous liver tissues of experimental group were 41.7% and 54.2%, respectively, with no significant difference between them (P > 0.05). No survivin expression was detected in the experimental group before 46th week, neither in the rats without HCC occurrence nor the normal controls. The level of survivin mRNA expression in HCC at 58th week was significantly higher than that in pre-HCC, no-HCC and normal liver tissues in the control group (P < 0.01). The level of survivin mRNA expression in para-carcinoma tissues was also significantly higher than that in no-HCC and normal liver tissues of the control (P < 0.01). The level of survivin mRNA in pre-HCC at 12th, 20th, 36th, 46th weeks were significantly higher than those in normal liver tissues taken from control group during the same periods (P < 0.01).

CONCLUSIONThe over-expression of survivin gene is related to the occurrence of HCC and may play an important role in the carcinogenesis of HCC.
